Vim li cas tus nqi tso tawm ntawm pH meter transmitter hloov pauv ntau heev
Lub pH meter transmitter hauv online muaj qhov tsis ruaj khov thiab hloov pauv qhov tseem ceeb, thiab nws ua haujlwm tsis zoo 2 teev tom qab cov txheej txheem ua kua calibration thaum pib siv. Qhov tshwm sim tshwj xeeb yog tias tus nqi pH ntawm qhov ntsuas nruab nrab yog nyob nruab nrab ntawm 6.8 thiab 7.2. Thaum tus nqi pH yog 6.8, lub transmitter tso saib tus nqi hloov pauv ntawm 5.9. Thaum tus nqi pH yog 7.2, lub transmitter tso saib tus nqi txo ntawm 11, thiab thaum nws poob rau 10, nws maj mam txo. Tom qab hloov lub transmitter tshiab, qhov tshwm sim no tsis tshwm sim.
Qhov teeb meem ntawm kev hloov pauv loj hauv cov khoom siv hauv online pH meter transmitters yog qhov tsis tshua muaj, thiab tsis muaj ntau yam teeb meem nrog cov pH meters txawv teb, uas qee zaus tshwm sim. Koj puas xav pom seb puas muaj kev sojntsuam tshiab? Txheeb xyuas qhov impedance nrog kev sojntsuam tshiab. Tsis muaj kev sojntsuam hloov, xyuas tus choj ntsev * Koj puas xav hloov qhov kev sojntsuam yav tom ntej. Tej zaum nws yuav yog vim xoob xaim, zawm cov hlua hlau terminals.
Lus Cim: Cov choj ntsev yog hais txog ib qho me me ntawm cov tshuaj KCl uas nkag mus los ntawm cov porous ceramics tom qab siv cov electrode tau muab tso rau hauv cov tshuaj ntsuam xyuas. Nws txuas nrog rau cov khoom siv hluav taws xob sab hauv thiab cov tshuaj ntsuam xyuas sab nraud, ua tus choj rau hluav taws xob tiv tauj, thiab hu ua choj choj. Tus nqi xau ntawm E ntsev choj kev daws teeb meem muaj feem cuam tshuam rau kev sib txuas ua kua muaj peev xwm: tus nqi xau qeeb ua rau tsis muaj peev xwm ntawm cov kua sib txuas; Tsis tas li ntawd, yog tias lub siab ntawm cov ntsuas ntsuas tau nce thiab qhov xau qis qis, cov tshuaj ntsuas tuaj yeem nkag mus rau hauv cov khoom siv electrode, ua rau lub ntsuas acidity malfunction.
